Conflict-of-interest disclosure: C.D.D. On the basis of the preliminary safety and efficacy data,18 2 venetoclax dosing schedules (400 mg and 800 mg) were evaluated separately in the expansion stage, in combination with either decitabine or azacitidine. The HOVON/SAKK study compared a double-induction concept using intermediate- or HiDAC as part of an induction/consolidation regimen in a phase III randomized study in patients (aged 18–60 years) with newly diagnosed AML (n=860).59 Patients were randomized to treatment with an “intermediate-dose” cytarabine regimen (12 g/m2 cytarabine; cycle 1: cytarabine, 200 mg/m2 daily for 7 days + idarubicin, 12 mg/m2 daily for 3 days; cycle 2: cytarabine, 1 g/m2 every 12 hours for 6 days + amsacrine, 120 mg/m2 daily for 3 days) or a “high-dose” cytarabine regimen (26 g/m2 cytarabine; cycle 1: cytarabine, 1 g/m2 every 12 hours for 5 days + idarubicin, 12 mg/m2 daily for 3 days; cycle 2: cytarabine, 2 g/m2 every 12 hours for 4 days + amsacrine, 120 mg/m2 daily for 3 days). Adult acute myeloid leukaemia. Coagulopathy is common at presentation in many leukemias; it is therefore standard clinical practice to screen for coagulopathy by evaluating prothrombin time, partial thromboplastin time, and fibrinogen activity as part of the initial evaluation and before performing any invasive procedure. Short NJ, Kantarjian HM, Loghavi S, . Esteve J, Schots R, Bernal Del Castillo T, . Patients with a history or symptoms of cardiac disease, prior or planned exposure to cardiotoxic drugs or thoracic radiation, or those of an older age should have an echocardiogram. Clofarabine doubles the response rate in older patients with acute myeloid leukemia but does not improve survival. Strategies for postremission are based on cytogenetics, molecular genetics, and potential risk of relapse, with higher-risk patients receiving therapy that is more aggressive, including allogeneic stem cell transplantation. Low-dose cytarabine resulted in a CR rate of 18% (vs 1% with hydroxyurea) and a survival benefit compared with hydroxyurea in patients with favorable or NK-AML. Outcome of induction and postremission therapy in younger adults with acute myeloid leukemia with normal karyotype: a cancer and leukemia group B study. Laboratory evaluations include a comprehensive metabolic panel and a complete blood count including platelets and a differential of white blood cells (WBCs). In a CALGB trial,46 the subgroup of patients aged ≤60 years (n=156) who received standard-dose cytarabine-daunorubicin induction therapy and 4 courses of HiDAC consolidation (3 g/m2 every 12 hours on days 1, 3, and 5, per course) experienced a 4-year DFS rate of 44%. In addition, the 2-year death rate in CR was significantly lower in the ambulatory arm (0% vs 5%; P=.04) and no difference was observed in the cumulative relapse rate between arms.76 Although the CALGB trial did not show an overall benefit for higher doses of cytarabine consolidation in older patients, a subset of patients with a good performance status, normal renal function, and a normal or low-risk karyotype might be considered for a single cycle of cytarabine (1.0–1.5 g/m2 daily for 4–6 doses) without an anthracycline.
Karyotypic analysis predicts outcome of preremission and postremission therapy in adult acute myeloid leukemia: a Southwest Oncology Group/Eastern Cooperative Oncology Group Study. The major reason patients are not cured is resistance to treatment, often manifested as relapse from remission, rather than, even in older patients, TRM, whose incidence is decreasing. United Kingdom National Cancer Research Institute Acute Myeloid Leukemia Study Group. Burnett AK, Russell NH, Hills RK, .UK NCRI AML Study Group. If an HLA-matched sibling or alternative donor has been identified, an allogeneic HCT may be effective in 25%–30% of patients with induction failure. KIT-D816 mutations in AML1-ETO-positive AML are associated with impaired event-free and overall survival. 2018. The median OS for venetoclax 400 mg with azacitidine was NR (95% CI, 9.0 months-NR), and for decitabine it was was 14.2 months (95% CI, 7.7 months-NR; Table 3).
Participants will earn MOC points equivalent to the amount of CME credits claimed for the activity. Duration of CR + CRi by venetoclax dose levels (dose escalation + dose expansion cohorts).
Blood 2013;121:4655–4662. For patients <60 years of age, postremission therapy is also based on risk status defined by cytogenetics and molecular abnormalities (see AML-11, page 726). Storb R. Can reduced-intensity allogeneic transplantation cure older adults with AML? Other anteceden… Patients who have persistent disease after 2 courses of therapy (including a reinduction attempt based on midcycle marrow) are considered to have primary induction failure. For this strategy to be better used, potential transplant options should be considered during induction therapy and alternative donor options/searches should be explored earlier in the disease management. Postremission treatment of elderly patients with acute myeloid leukemia in first complete remission after intensive induction chemotherapy: results of the multicenter randomized Acute Leukemia French Association (ALFA) 9803 trial. The induction strategy is influenced by individual patient characteristics such as age, cytogenetics, molecular genetics, presence of comorbid conditions affecting performance status, and preexisting hematologic disorder (MDS, myeloproliferative disorder), and prior cytotoxic or radiation therapy. Haematologica 2015;100:780–785. Key exclusion criteria were prior HMA treatment or chemotherapy for antecedent hematologic disorders (treatment with other agents excluding hydroxyurea for myelodysplastic syndrome or myeloproliferative neoplasm was permitted), favorable-risk cytogenetics (per 2014 National Comprehensive Cancer Network Guidelines),20 known active central nervous system involvement, and concomitant use of strong or moderate CYP3A inducers or inhibitors within 7 days before study drug administration.
Optimization of chemotherapy for younger patients with acute myeloid leukemia: results of the medical research council AML15 trial. Single-agent GO has also been evaluated as an option. To mitigate any potential tumor lysis syndrome, patients were required to have a WBC count of at least 25 × 109/L at study initiation, with the use of hydroxyurea allowed to meet this criterion, and all patients required hospitalization, hydration, and treatment with a uric acid-reducing agent before and during the first few days of treatment. Describe outcomes of patients with relapsed Acute Lymphocytic Leukemia. If no response or progression is seen, a clinical trial, therapies for R/R AML, or best supportive care are recommended treatment options. Grimwade D, Hills RK, Moorman AV, .National Cancer Research Institute Adult Leukaemia Working Group. Patients undergoing SCT (n = 21) were not censored from CR/CRi and OS analyses. The role of measurable/minimal residual disease detection in AML is currently under active investigation. Blood 2003;102:1232–1240. A randomized phase III study evaluated the efficacy of single-agent GO (6 mg/m2 on day 1 and 3 mg/m2 on day 8) versus best supportive care as first-line therapy in older patients aged ≥61 years with AML who were not eligible for intensive chemotherapy (n=237).106 Compared with best supportive care, GO alone improved the 1-year OS rate (9.7% vs 24.3%, respectively).

A shortened form of the model was based on covariants that include age, performance status, and platelet count. Clinical response and miR-29b predictive significance in older AML patients treated with a 10-day schedule of decitabine. The expression of both cytochemical and/or immunophenotypic characteristics of both lineages on the same cells is defined as biphenotypic, whereas expression of lineage-specific characteristics on different populations of leukemia cells is termed bilineal.

Phase II, multicenter, randomized trial of CPX-351 (cytarabine:daunorubicin) liposome injection versus intensive salvage therapy in adults with first relapse AML. The third phase III trial combining GO with chemotherapy showed a different result than the other two. Farag SS, Ruppert AS, Mrózek K, . Powered by the EthosCE Learning Management System, a continuing education LMS. A.L. In another multicenter, phase III, randomized trial from the United Kingdom and Denmark (AML-16 trial), patients older than 50 years with previously untreated AML or high-risk MDS (n=1,115) were randomized to receive daunorubicin-based induction (daunorubicin combined with cytarabine or clofarabine) with or without (control) GO (3 mg/m2 on day 1 of course 1 of induction).85 The median age was 67 years (range, 51–84 years) and 98% of patients were aged ≥60 years; 31% were aged ≥70 years.

In addition, patients with de novo AML and secondary AML, respectively, had the same CR/CRi rate of 67%, with a median duration of CR/CRi of 9.4 months (95% CI, 7.2–11.7 months) versus NR (95% CI, 12.5 months–NR).101. Kayser S, Döhner K, Krauter J, .German-Austrian AMLSG. Röllig C, Bornhäuser M, Thiede C, . Mutations associated with AML were detected by next-generation sequencing using the FoundationOne Heme panel (Foundation Medicine, Cambridge, MA) for patients in the dose-escalation cohort, the MyAML panel (Invivoscribe, San Diego, CA) for BM aspirate specimens of patients in the expansion cohort, and/or the TruSight Myeloid panel (Illumina, San Diego, CA) for peripheral blood. In a report of 122 patients treated with HiDAC and daunorubicin, the remission rates were strongly influenced by cytogenetics, with CR rates of 87%, 79%, and 62% for favorable-, intermediate-, and poor-risk groups, respectively.49, In the MRC AML 15 trial, younger patients with untreated AML (median age, 49 years), were randomized to 2 induction courses of (1) daunorubicin and cytarabine with or without etoposide (ADE; n=1,983), or (2) ADE versus fludarabine, cytarabine, granulocyte colony-stimulating factor, and idarubicin (FLAG-Ida; n=1,268).50 In consolidation, patients were randomized to amsacrine, cytarabine, etoposide, and then mitoxantrone/cytarabine, or HiDAC (3 g/m2; n=1,445).50 Patients in the HiDAC arm received 1.5 g/m2 in consolidation and were treated with or without a fifth course of cytarabine (n=227). A reasonable treatment regimen for patients with favorable or intermediate risk cytogenetics includes standard-dose cytarabine (100–200 mg/m2 by continuous infusion per day for 7 days) along with 3 days of anthracycline.

Wordingham, M.D. In addition, preliminary results of key exploratory analyses, such as measurable residual disease (MRD), are described. In the CALGB 10603/RATIFY Alliance trial, patients aged 18 to 59 years, with newly diagnosed FLT3-mutation–positive AML (ITD or TKD) were randomized (n=717) to receive standard cytarabine therapy (200 mg/m2 daily for 7 days via continuous infusion) and daunorubicin (60 mg/m2 on days 1–3) with placebo or midostaurin (50 mg, twice daily on days 8–21).32 If residual disease in the bone marrow was observed on day 21, patients were treated with a second blinded course. If the patient did not receive HiDAC for persistent disease at day 15, HiDAC with or without anthracycline may be used if a clinical trial is not available and a donor is not yet identified.
